Energy Savings, Superior Performance

Rinnai direct vent wall furnaces are designed to constantly monitor room temperature and respond immediately to temperature fluctuations. This ensures you have the ultimate in even, consistent heat while still saving energy.

When the unit senses a drop in temperature, it begins to warm the room. The variable fan speed and BTU output increase as necessary to achieve the set temperature. Once the room has reached the desired temperature, fan speed and BTU output decrease.

Built to Last

Rinnai products are designed to provide years of quality operation. The EX38 carries a 10-year limited warranty on the heat exchanger (for residential installations), a 5-year warranty on parts and a 2-year warranty on labor.
